Body
I installed new version of eclipse Kepler instead of Indigo. My current OS is Ubuntu 12.04. All looks fine and setting Ubuntu update the same as was at Indigo. But some <code>error</code> happens when I try to run easy program: <pre><code>package polymorphism; class AlertStatus { public String getStatus() { return "None"; } } class RedAlertStatus extends AlertStatus { public String getStatus() { return "Red"; } } class GreenAlertStatus extends AlertStatus { public String getStatus() { return "Green"; } } class YellowAlertStatus extends AlertStatus { public String getStatus() { return "Yellow"; } } class Starship { private AlertStatus status = new RedAlertStatus(); public void setStatus(AlertStatus aStatus) { status = aStatus; } public String toString() { return status.getStatus(); } } public class StarshipDemo { public static void main(String[] args) { Starship starfish = new Starship(); System.out.println(starfish); starfish.setStatus(new GreenAlertStatus()); System.out.println(starfish); starfish.setStatus(new YellowAlertStatus()); System.out.println(starfish); } } </code></pre> Here is error message: <pre><code>Error: Could not find or load main class polymorphism.StarshipDemo </code></pre> I couldn't figure out why this error happen and how to avoid it? Here is <code>java -version</code>: <pre><code>nazar_art@nazar-desctop:~$ java -version java version "1.7.0_40" Java(TM) SE Runtime Environment (build 1.7.0_40-b43) Java HotSpot(TM) 64-Bit Server VM (build 24.0-b56, mixed mode) </code></pre> Questions: <ul> <li>Why exactly this error erase? </li> <li>How to solve this trouble?</li> </ul> Update: I solved this by save before running program: <pre><code>Ctrl + S => Ctrl + F11 </code></pre> All is working perfect now, but why this exactly happen? At Indigo version I could fixed code and rerun (<code>Ctrl + F11</code>) at any time and all was re-recompiling and executing again. Does exist any way to circumvent this "save" part?

A row detail

Detail views are divided into sections. All the information in the data section comes from columns in the selected row. The other sections display data from other, related rows.

Related data can be related in a to-one or a to-many fashion. Captions of data related in a to-many fashion link to a list view showing a filtered view of the table.

Try moving around until you find a non-empty to-many entry and click on the label to get to one. You can move back to the root by clicking on the database name in the header.
